Specification of Letters Patent.

Application filed February 17, 1914. Serial No. 819,160.

To all ifi/wm my einem Be it known that we. .loHN Kiiwi'oz and (hims'rrxx H. T. HAoELs'rEtN, citizens of the YUnited States, residing at Hyde Park. in Norfolk county, and at Dorchester. in the county oi" Snii'olk, respectively. and State nl' l;i .-z\ rlii1s.rtt,s. have invented certain new and useful improvements in luttin-tihrliing Machines, of which the following is a speeilicatiiin. reference being had therein to the accompanying drawing.

This invention relates to button attaching inafhines. and more particularl)r to -machinees for attaching a series of shank-eye buttoir-y by thread or the like to a piece ot' work such as a shoe or other garment.

For convenience the present invention is illustrated as applied to the same general type o l button attaching machine which has heretofore been patented to us. although the norel features hereof might he applicable in other types .lf machine.

The principal obiect hereof is to perfect the construction and operation ot' button attaching machines for rendering them more eliicient. more certain in operation and more simple to handle and adjust.

Other and more particular objects will be Adeveloped in the hereinafter following description ot' an illustrative machine embodying the iinprovenicnts.

To the attainment of the objects referred to. this invention consists in the novel combinations. arrangements. devices. nieclianisms. details and other features shown or described herein.

Fig. l1 is a perspective View of the button agitating member in the reservoir.

Similar reference numerals designate corresponding parts in the severa-l views.

T he work ll' may be considered as a portion of a shoe to which a series of buttons are to be successively attached by thread. The general parts of the machine include a base supportingabove ita head '21 eX- tending laterally to form an overhanging arm 22,'in which is supported the main shatt 23. Beneath the work is a work-support. 2l which may be movably held in a housing or bracket :'25 and actuated by suitable mechanism from a cam 26 on the main shaft. the work-support lowering slightly during feeding of the work andA lifting during needle operations to clamp the work. Beneath the work also is a thread wheel 29,

shown located on the bracket also a 1 looper 30 suitably supported and actuated from a cam 31 on the main shaft.

The details of the thread mechanism and the cooperation thereof with the feeding and button supplying devices need not be l'ully described as they are generally wellknown. The preferred operation, however, ot' the machine will now be set forth. The operation may be as set forth in prior Patent No. 1.063.885 and other analogous prior patents. A button having been fed to a point above the work and beneath the needle with the shank eye of the button positioned horizontally. the hooked needle makes its lirst descent through the buttons eye and through the work t0 where the thread, supplied from below. is fed to the needle. which thereupon ascends drawing a primary thread loop through the buttons eye. Thereupon the needle descends a second time. through the primary loop but outside the buttons eye, either the needle or the work and button having been slightly displaced in the meantime. The needle, penetrating the work a second time, is supplied wlth a secondary thread loop below the work, and. on ascending, the lneedle draws the secondary loop through the primary loop and tightens the latter. Then the needle is at its upper position the spreader comes into play to engage the secondary loop, which the needle thereupon disengages, for example, by a slight relative movement toward and from the spreader, permitting the 4latter to place the thread loop over the head of the button, the spreader tipping down and shedding the loop, which is' then tightened lby suitable take-up devices, so that the two loops and button shank, now interlocked, are securely drawn to the fabric and the loops formed into a knot. Thereafter, the work being fed forward the required distance. the succeeding button is similarly treated with the same thread, so that eventually7 the entire series of buttons is properly secured by stitching to the work.

One feature of improvement shown herein is an apron 32 slightly below and forward of the work-support, it consisting of a hollow box-like structure adapted to be moved out of and into position, so as to permit access to the thread wheel Q9 and other Working parts while protecting the work from being injured or soiled by the working parts. A convenient way of movably mounting the apron 32 is by means of a spring hinge 33, Fig. 1, permitting the apron to be swung to the right, its open position shown in dotted lines in Fig. 2.

The work may be fed between operations in any suitable manner, for example, by a feed prong 34 constructed and operated in a well-known manner.

The illustrated parts below the work have now been fully referred to.

The main shaft at its right end is surrounded by a loose belt pulley 40, which may at will be coupled to or uncoupled from the shaft by a suitable clutch device located at 41.

The needle, 44 may, as'usual, be of the i hooked straight form and secured at the -be adjustable toward and from each other and adjustable in height. An improved feature shown is the contour of the opposed halves of the presser-foot such that each button standing therebetween is upheld in a vertical position, so as to insure the proper spreading of the secondary thread loop over the button. By so constructing the presserfoot, movable devices to uphold the lgruttony are dispensed with.

Coperating with the needle is shown a cast-off 5,1, which may be of usual type and supported on a cast-0H bar 52 which receives its" proper up-and-down movements in a usual way through coperating lugs on the needle bar and east-off bar respectively, aided by a spring retaining device 53. Also eoperating with the needle and other described parts may be employed the usual spreader 55, which swings in to take the sec,-l ondary loop from the hooked needle, spread the loop open and then tips to shed the loop over the button. An arm on the spreader may be contacted by a movable device 56 for tipping the spreader against the resistance of a spring 5T in a manner already known and not claimed par se herein.

Another improved feature shown herein is a novel form of needle backing device 60, more particularly' show i in Fig. 5. This is purely self-acting, ending no attention nor any cam operation. It isA shown pivoted at 61 between the two halves ofthe biturcatl ed presser-foot and having a rear stop arm 62 engaging a stop pin 63 when in normal position, as shown in full lines. A coiled spring 6l, having one end fastened to a fixed place and the other end to the hacker 60, serves to press the latter with sullicient force to hold it normally securely in the position shown. The needle hacker itself is in the form of an arm which, when in normal position, extends in a direction substantially at right angles to the needle, the extremity of the baeker being of suitable needle engaging form and contacting directly behind the needle. The particular importance of this feature is the protection of' the needle against deflection or continually repeated deflections as a bending tendency is applied to the needle. While a needle will resist displacement and will restore itself to normal position upon a small deflection, it is found that deliections repeated many times eventually cause a permanent strain, sothat the needle slightly loses its shape, and this may, by improper cooperation with other parts, bring about irregular or unsatisfactory button attaching results or even conflict and breakage of parts.

Particularly it is true that the spreader 55, when swinging rearwardly to enter the secondary thread on a needle, causes a serious stress. The spreader` not only tightens the loop by tendingto spread it, but actually moves rearward, so that there is a decided tendency to bend the needle to the rear during -the attachment of each button.

The backer 60 effectively lprotects the needle against permanent bending or injury in this respect. Moreover, the backer automatically places itself in operative position for theA purpose and yet is able to yield at suitable times, so as not to interfere with the ieu proper operation of the needle. Thus, on each descent of the needle, the needle bar 45, which otherwise might confiict with the needle backer, is able, owing to the yielding nature of the latter, to swin it downward to the dotted position shown 1n Fig. 5.

The button supplying means includes a suitable elevated button reservoir, a button chute leading therefrom to the sewing position, agitating means within the reservoir for causing buttons to enter the .chute and button clamp means at the lower extremity of the chute for holding each successive button inl proper attaching position relatively to the work and needle.

'I he general arrangement of the reservoir and the chute 100 may be as4 indicated in said prior Patent 1,063,885, the chute being movable relatively to the reservoir and the latter being adapted to be swung over about a pivot 72 for dumping out the buttons.

The reservoir 70 has a cover 71 openable for inserting and removing buttons which are supposed to be suppliedin bulk and fed singly in orderly position to the passages leading from the reservoir to the chute. Fig. 1 shows the position of the reservoir and the oscillating agitator shaft 73, which operates the devlces Within Vthe reservoir. The agitator shaft connections will be later described. The further details of the reservoir are better shown in Figs. 4, 8, 9, 10, and 11.

Fig. 3 shows that the reservoir is bodily tipped so as to incline downward at the right, tending to carry the buttons b gravity to the lower right-hand corner. nstead of having a simple cup shape, the reservoir is preferably constructed with a wall 75, whichis curved both horizontally and vertically, as indicated by the top view, Fig. 8, and also the left-hand elevation, partly in section, of Fig. 9. By this arrangement gravity tends always to bring thebuttons to the general position indicated at 7 6 in front of the oscillating agitator device.

The agitator device hereof comprises several elements, all carried by the agitator shaft 73. Extending downward from the shaft 73 is an arm 77, having an arc shaped button lifter 78 at its extremity, and-a button pusher 79 in the form of a curved plate extending laterally, asbest shown in perspective in 11. The shaft also actuates a forwardly extending member 80, which on each downward stroke tends to strike or force down any buttons which have been lifted too far or failed to enter the outlet passage 'llie button lifter 78 and the am: 77 carryin',r it extend between the right-bind wall of the reservoir and the interior curved 'Wall 75, the lifter 78 moving from che curved wall into the interior of the reservoir at its lowest portion, as to force a number of buttons upward at eacn oscillation, whereby one or more buttons will usually take a suitable posture to fall within the button exit shown at 81.

The member 80, which moves downwardly fer dislodging accumulated buttons and assisting the entry of buttons into the eXit passage, may consist of a tightly coiled spring screwed or otherwise secured upon a pin projecting from a supporting member 82 secured to the agitator shaft 73. The introduction of the spring SQ's of considerable importance in not only increasing the durability of the device but in preventing breakage, which might occur with a rigid member employed to kick the buttons downwardly. The use of the spring itselfv for kicking the buttons gives a light touch or blow and avoids injury to the buttons themselves.

The button pushing plate 79 extends beneath the curved plate or between that and the bottom ofthe reservoir. Fig. 8 shows the curved pushing plate in retracted position. Its purpose is to cause the remaining buttons, when the reservoir is almost empty, to be fed forward and downward into a position in front of the lifter so that the latter may properly act upon the buttons, as described.

By means of the described agitator including the three coperating portions, it is found that not only is great durability and ease of action secured, but efficiency and ability to cause all the buttons supplied to vthe reservoir, including the very last button,

to be fed to the exit passages and thereby to the chute which leads to the attaching position.

` The exit passages of the reservoir are shown in dotted lines, Fig. 9, as leading downward, and, as seen in Fig. 6, they are in'register with the passages in the' chute 100, so that` the fed buttons are properly passed from reservoir to chute.

I The "agitato-r shaft portion 73 is shown connected by adisconnectible spring clutch device 85 with` a second vshaft portion 86 in alincment therewith. The details and operation of the clutch device are explained in said prior Patent' 1,063,885. The shaft portion 86 inc-.lines downwardly toward the driving end of the main shaft and at its extremity is provided with a swinging arm 87 connected by a link 88 with a vertical arm 89 at the rear of the machine. the latter pivoted to a fixed `standard 90 at its lowrr -end and having at an intermediate point a stud 91 engaging in the groove of a cam 922 attachedto or formed in one part with the belt pulley 40. By' this arrangenu-nt the parts 89, 87, 86, 73. 78. 79, and S' are continuously oscillated whether or not buttons are being attached, so that. han Mic attaching mechanism stands idle. the Butt' n fearline` means is operating to supply the chute with an extended series ot' buttons ready for subsequent operations.

The, chute 100 may consist of two parts between which the button heads pass and oml or both of the parts being kerfed to guide the button shank. The left-hand chute part 101 and the right-hand chute part 102 are shown in cross-section in Fig. t5 with the button lw between them. while in 1 and the chute section 101 is shown journaled by a horizontal pivot shaft 103 to permit the lower'end of the chute to s\\-'ing forwardly and rearwardlv from and toward the button attaching position. The space between the two chute sectionsl may be adjustand the right-hand end plate 105. which engages with a device carried by the movable chute section 102. so that. under the liniuence of spring 10T. the plate 105 partakes of the adjustment of the chute. By these adjusting devices` buttons having various sized heads may be acconnn:dati-d.

lleferring now more particularly to the means of adjusting the chute opening. the same, is best illustrated in Figs. I?) and l. A novel feature of improvement is the employment of a pair of cooperative adjusting devices located at removed points on the length of the chute and actuated in unison to cause the chute sections at both ends and at all parts to simultaneously approach or recede. thereby insuring` accurate and uniform adjustment. For this purpose it is preferred to employ a pair of screw devices 110. 111. each of them rotativeiy fitted in the chute sectimi 102 and each having` screw-threaded connections. as shown. with the chute section 101. By now turning the screw devices 110. 111. equal amounts the chute sections at all points and thel reservoir plate 105 will equally and uniformly adjust for different .sized button heads. This result is herein shown as accomplished by means of a connecting link 112 extending from a disk or wheel on the screw device or wheel 113 to the arm 11-1 on the screw 111. The disk 113 on the upper screw may take the form of a knurled wheel or head. as shown. to facilitate manual adjustment of the parts. By now turning the head 113, the link 112 is moved up or down and the two screws 110. 111. arey equally rotated. Each screw has a high pitch. so that a partial revolution will give the maximum amount of throw desired for any chtite adjustment.

The adjustingI devices may be calibrated as by means of a scale shown at 115, So as to predetermine various chute Widths, and

a locking device may be employed in the form of a screw 11G engaging a circular Slot in the disk 113. the screw being loosened to permit adjustment and tightened to lock the parts.

Another illustrated feature of improvement herein is the combination with the chute of means` for normally restraining the buttons from passing out at the lower end and means whereby the passage may be `opened to permit the buttons to freely run out for the purpose of emptying the chute when desired. Normally the buttons are restrained by a yielding stop 130. hereinafter to be more fully described. ln order to permit the free exit of the buttons when desired, it is preferred to provide a movable chute portion 119. preferably a part of the right-hand chute .section 102. which is at the lower side of the incline chute. The portion or block 110 may. for example. be titted to swing about a pivot 121. it having` a. stop screw 12() for insuring its accurate position when closed. Fig. shows in full lines the normal position of the parts, and in dotted lines the block or gate shown open at 110, lVhen the ch'ute is thus` opened. the buttons` in the chute freely run out. tl is permitting inspection. repair and adjustment or the replacement of the buttons by buttons of a different character. 'hen the gate is closed. it fits solidly into position. restoring the continuity of the chute passage. and is there firmly held by a locking device 122. The device 122 swings about a pivot 123 at right angles to the pivot 121. For convenience. the pivot 12S may be concentric with the pivot of the arm 111. before. referred to. The device 122 has a tinger piece 12aL by which it can be moved between its operative position shown in Fig. I1. and in full lilies in Fig. 1, or its inoperative position. shown in dotted lines in Fig. 4. The finger piece 12-1 has a projection 125 which lies against the front surface of the block 119. as seen in Fig. 3, when the parts are locked in normal position. The operator. by pulling the linger piece 12-1 forwardly, releases the gate or block 119. which may then be swung' out from the chute for the purpose specified. The device 122 is of a spring character so as tovgive it frictional pressure against the gate 119 when the parts are locked.

The stop device 130, at the extremity of the chute. is of an improved construction. It is adapted to stand in the path of the Shanks of the buttons. The buttons descend in succession and the shrnks, as usual, project horizontally through the left-hand opening in the chute portion 101. The

yielding stop is so positioned as to contact the button Shanks and thereby position them directly beneath the needle 44. The button shank stop 130 s shown 1n the form of a swinging platepivoted at 131 and havving an extension 132 to which a convenient forni of spring 133 is attached, so as to hold vbutton aiid-the chute relatively the stop 130 in the position shown iii-Fig. 5, yet to permit its `yielding as the foremost separate. As Vthe work feeds toward the rear or as the chute retracts toward the front, the button passes-out of the chute, this action taking ',place between the formation of the primary Wthreazclioop and the final spreading of the secondary loop over the head of the button,

l which at that time must be free.

. :Coming now to the yielding stop 130 for the shaiiks of the buttons, -that is best shown in Figs. .5 vand T as consistingl of alight me l tallic plate pivoted at 131 and having an extension 132, acted on by a spring 133 to hold the stop normally in the vposition indicated.

-K The buttons, descending toward the extremity of the chtite, have their slianks outstanding horizontally from the slot, seen in Fig. and the shank of the foremost button comes into contact with the stop 130, which accurately positions it beneath the needle 11, so that, when the button is clamped, it is so held that there can be no conflict in operation or breakage of parts. Un the other hand, the stop 130 readily yields to permit the button to pass out of the chute'at the proper time.

lIn addition to the but-ton shank stop 13()y is'sliown a yielding button headstop 135 associated with the button head clamp 136, `arranged and operated in a manner generally similar to the stop and clamp in' said prior Patent 1,063,885.- In the present machine the button head clamp 13G is made of :increased horizontal dimension or width, so #that it not merely Aclamps the button being attached, btit'acts upon the head of the succeed'ing' button lto force it slightly back,

'iiei'enting interference. The clamp 136 swings lupon a 'pivot stud 137 projecting "frotnthe chute section'llOQ, while the stop 13.1 swings on a stud 13S carried on the clamp 13G. A spring 139 holds the stop 135 yieldingly in aposition slightly outstandingwith rlespect to the clamp 136, as seen inv Fig. '7,"ivhere the stop is in full lines and the clamp is shown in dotted lines behind it. rflie'clamp 136 has an operating extension 110;. a spring 111 serving to normally hold -it lightly in retracted position, sothat the buttons may descend freely to lowermostV ton lifting point therein of the clamp'lSG so as to lock foremost button in attaching fore the descent of the needle primary loop.

s usual, the chute has an extension 150` Fig. 1, to the rear whereby it may be swung forwardly and rearwardly in harmony with the other operations of the machine, and this extension 150 may be suitably connected with a crank shaft 151 (see Fig. 1) whereby the main shaft controls the oscillation of the chute. I i

lt will thus be seen that there has been described a button attaching machine embodying the improvements and attaining the objects and advantages above recited,and other advantages therein will be apparent to kthose skilled' in the art.
